Household adoption of ecological sanitation : an assessment of agricultural value and user perspectives in Nyanza Province, Kenya
(Massachusetts Institute of Technology, 2005)
Ecological sanitation, or ecosan, refers to a range of sanitation technologies in which human excreta is recovered and retained on-site, and eventually reused. However, when a culture does not have a tradition of reusing ...
Innovation in the AEC industry through wireless sensor networks
(Massachusetts Institute of Technology, 2005)
I came to the Massachusetts Institute of Technology (MIT) to learn about technological innovation and entrepreneurship. More precisely, I wanted to know more about how to leverage Information Technology (IT) in the ...
Appropriate water treatment for the Nyanza Province of Kenya
(Massachusetts Institute of Technology, 2005)
In 2000 the Centers for Disease Control and Prevention (CDC) in conjunction with CARE International began working with several local non-governmental organizations (NGOs) in the Nyanza Province of Kenya to reduce the rate ...
Structural feasibility of a medium-rise timber office building
(Massachusetts Institute of Technology, 2005)
Using timber as a structural material for commercial projects will certainly gain importance and popularity in the coming decades as more focus is placed on reducing environmental effects created by a dependence on steel ...
Design considerations for retractable-roof stadia
(Massachusetts Institute of Technology, 2005)
As existing open-air or fully enclosed stadia are reaching their life expectancies, cities are choosing to replace them with structures with moving roofs. This kind of facility provides protection from weather for spectators, ...
Corrosion resistance of concrete reinforcement
(Massachusetts Institute of Technology, 2005)
The objective of this thesis is to investigate the mechanism of corrosion of steel reinforcement in concrete and epoxy coated reinforcing bars as corrosion resistant alternatives. Several case studies explore the durability ...
Safe water storage in Kenya's modified clay pot : standardization, tap design, and cost recovery
(Massachusetts Institute of Technology, 2005)
One of the main components necessary for providing safe drinking water for users who lack piped water in the home is the ability to safely store it in the home. Users in the Nyanza Province of Kenya frequently carry water ...
An evaluation of household drinking water treatment systems in Peru : the table filter and the safe water system
(Massachusetts Institute of Technology, 2005)
(cont.) storage, and education. Tests on the SWSs in Peru demonstrated 99.6% E.coli removal and 95% total coliform removal. Only 30% of the SWSs tested contained water at or above the WHO-recommended concentration of free ...
A performance study of ceramic candle filters in Kenya including tests for coliphage removal
(Massachusetts Institute of Technology, 2005)
Approximately 80% of all diseases in the developing world are caused by contaminated water (GDRC, 1999). In response to this crisis, decentralized point-of-use systems, such as ceramic candle filters, have emerged as viable ...
Low-impact development in the Assabet River Watershed : site hydrologic design and watershed-scal implications
(Massachusetts Institute of Technology, 2005)
Low-Impact Development (LID) is a relatively new approach to stormwater management. It aims to mimic natural hydrology through increased recharge and decreased runoff. LID technologies focus on distributed treatment of ...
